I have a minty Nikon FT-1 mount adapter that I no longer need. It allows you to mount a bewildering number of great Nikon lenses on the 1 series cameras to take advantage of the 2.7x crop factor. They are $210 brand new. This is close to new as you can get and I am asking $150. (or best reasonable offer)DSCF9289 by Luke Lavin, on Flickr
